What means chemical skin peel for acne?
A chemical peel for acne is a treatment in which an acid solution is used to remove the damaged outer layers of the skin. In performing chemical peels, physicians apply alpha hydroxy acids (AHA), trichloroacetic acid (TCA), or phenol to the skin.
What they are?
Chemical skin peel for acne can be administered by doctors in up to 70% concentration/strength, or in up to 30% concentrations by aestheticians in spas and salons. Chemical peels are acids which are applied to the skin about once every two weeks. These acids chemically exfoliate the top layers of skin. This exfoliation signals the cells inside the skin to produce more rapidly, which can help hasten skin turnover and prevent pores from becoming clogged. At this time there is no evidence showing whether any one type of peel works better than another. From the date we currently have, they all appear to have similar efficacy. Chemical face peels are also sometimes used to help lessen the appearance of acne scars.
Do they work?
Studies show about 45-50% reduction in acne lesions after a series of 4-6 peels. Most study participants report a “fair” to “good” result. Results tend to last for 1-2 months, with acne beginning to reassert itself at this time.
Side effects of chemical peelsMost people experience a sun burnt look with obvious peeling of the skin in the days after their first peel. This redness and skin peeling tends to be less pronounced with each consecutive peel. Temporary darkening of the skin has been reported, and some people with darker skin have experienced skin lightening which can be permanent. Because people with darker skin and people who are prone to keloid scarring are more likely to experience side effects from chemical peels, it is vital that people with darker skin consult with an experienced dermatologist before embarking on chemical peels. A 2012 article published in the Journal of Cutaneous and Aesthetic Surgery sums it up: “Usually, complications are minor and more common in dark-skinned individuals. They are seen more in medium and deep depth peels.”
Because a chemical peel reduces the protective layer of the skin, your skin will be much more sensitive to sunlight and UV rays. It is extremely important to keep your skin out of the sun after a peel and to use an adequate SPF.
Best Chemical Peel?
Generally, fair-skinned and light-haired patients are better candidates for chemical peel treatments. If you have darker skin, you may also have good results, depending upon the type of problem being treated. But you also may be more likely to have an uneven skin tone after the procedure.
Skin sags, bulges, and more severe wrinkles do not respond well to chemical peel. They may need other kinds of cosmetic surgical procedures, such as laser resurfacing, a facelift, brow lift, eyelid lift, or soft tissue filler (collagen or fat). A dermatologic surgeon can help determine the most appropriate type of treatment for you.
Most chemical peels appear to help clear most types of acne. However, the dermatological community’s consensus is that other medications and treatments must be used in conjunction with peels to achieve a satisfactory level of clearance.
